Advanced automated processing and detection algorithms

Our comprehensive data analysis software suites are continually developed and improved to keep abreast of innovations in the field and our own internal research programs. We use high-performance computing clusters to efficiently and reliably process large volumes of acoustic data to provide:

Automated detection and identification of marine mammal calls

Ambient sound level calculations

Seismic survey event detection and quantification

Vessel sound detection and quantification

Pile-driving sound detection and quantification

Our specialized bio-acousticians review samples to confirm the automated marine mammal detections and identifications; they also interpret the vocalization data in the context of the given project and environment.

Specialized manual analysis

Our specialized bio-acousticians review audio samples and spectrograms to confirm the automated marine mammal detections and identifications and to interpret vocalizations in the context of the given project and environment. Analysts review the data to:

Identify presence or absence of vocalizations for marine mammal species of interest

Classify marine mammal calls by species and call type

Identify presence or absence of seismic survey activity

Characterize the time and frequency parameters of acoustic events

Our manual analysis protocols are customized to meet the needs of your project.

Real-time analysis: passive acoustic monitoring

JASCO analysts provide real-time passive acoustic monitoring (PAM) solutions in the field. The experienced PAM operators listen to the acoustic data and inspect the spectrograms of the measured sound levels in real time. They log all anthropogenic noise events and marine mammal calls and can immediately notify survey operators of marine mammal detections. The raw data and a brief detection report can be provided immediately.
